A situation in which a comedian comes up with some original material (he is ast the top of the pyramid, and other fellow comedians steal the material and change it around just enough to avoid plagiarism. (they are the next level down from the top of the pyramid). The process continues, cascading in a downward direction, making the pyramid larger.

That Bastard stole my joke! Now i have to deal with another Comedy Pyramid again!

when a comedy act goes through a cycle of being: 3 - 5 "ok" comedians, 2 - 3 funny comedians, 1 - 2 Hilarious Comedians, Thus building what we might call a pyramid. It makes a pyramid to the funniest comedian at the show.

man, last nights show was an awsome comedy pyramid! it was kinda good at first and kept getting better and better till the end!
